Al Qaeda's number two leader, Ayman al-Zawahiri, confirmed that the "Afghan Arabs" did not receive any U.S. funding during the war in Afghanistan. In the book that was described as his last will, Knights Under the Prophet's Banner, which was serialized in December 2001 in Al-Sharq al-Awsat, al-Zawahiri says the Afghan Arabs were funded with money from Arab sources, which amounted to hundreds of millions of dollars:
"While the United States backed Pakistan and the mujahidin factions with money and equipment, the young Arab mujahidin's relationship with the United States was totally different."
"... The financing of the activities of the Arab mujahidin in Afghanistan came from aid sent to Afghanistan by popular organizations. It was substantial aid."
"The Arab mujahidin did not confine themselves to financing their own jihad but also carried Muslim donations to the Afghan mujahidin themselves. Usama Bin Ladin has apprised me of the size of the popular Arab support for the Afghan mujahidin that amounted, according to his sources, to $200 million in the form of military aid alone in 10 years. Imagine how much aid was sent by popular Arab organizations in the non-military fields such as medicine and health, education and vocational training, food, and social assistance ...."
"Through the unofficial popular support, the Arab mujahidin established training centers and centers for the call to the faith. They formed fronts that trained and equipped thousands of Arab mujahidin and provided them with living expenses, housing, travel and organization."

Abdullah Anas, an Algerian who was one of the foremost Afghan Arab organizers and the son-in-law of Abdullah Azzam, has also confirmed that the CIA had no relationship with the Afghan Arabs. Speaking on the French television program Zone Interdit on September 12, 2004, Anas stated:
"If you say there was a relationship in the sense that the CIA used to meet with Arabs, discuss with them, prepare plans with them, and to fight with them -- it never happened."
